Check_MK FreeBSD agent updates coming

Check_MK FreeBSD Agent

A lot of work from Max M. (from the cmk list) and me and I’m getting to a point where the new FreeBSD agent will be ready for commiting.

Changes

use statgrab instead of MUSE

use statgrab instead of netctr

use statgrab inline from the main script

no more overflow bugs in memory consumption

removal of many unnecessary linux portions

plugin for portaudit

much smaller footprint

TODOS

Only one of those is really in the way, the rest are for later versions

Port packaging (I wanna upstream it both ways)

stdin closure – I had to open stdin due to an issue with statgrab. It will not print out the link status without opening stdin. This is a horror bug! Recommendation is to only use the agent in push mode, pushing to a server or via cron and a buffered file. Otherwise you might be inviting attackers.

add a plugin to HP raid controllers, currently using cciss_vol_status

add something for vmware tools status

GEOM status

ucarp

What I couldn’t find is anything to monitor ucarp – it kinda assumes monitoring is done via Email.

I’m thinking about a service for virtual IPs and have that as a clustered service between the cluster nodes.
